Don't think that style headstock inlay came along til 89ish so should be 95 using the usual serial format but I think that changed in the 90's and they weren't doing as many Gibson models later on.

I was surprised it sold for less than 50K espicially as they're rare and the case was included. Certainly won't pick up a Gibson Morc Bolan model for $411, probably more like $6000 and I bet it plays and sounds just as good or certainly not $5600 worse
